In this way, the noise can be better absorbed or scattered, reducing the noise energy of transmission and reflection, and achieving the effect of reducing noise. The anti-slip strips 141 arranged on the two support plates 14 can perform anti-slip treatment on the high-pressure fan 15 to prevent the high-pressure fan 15 from vibrating and sliding during operation. The chimeric design of the first plug plate 11 and the side mounting plate 2 makes the device more convenient to install and disassemble. At the same time, the blocks 21 arranged at both ends of the two side mounting plates 2 are also for the convenience of inserting the sealing plate 3 therein, and the ventilation net 31 installed on the sealing plate 3 can wrap the device without affecting normal operation.

[0026] See also Figure 1-5In order to make the noise reduction effect of the device better, a top plate 4 is jointly embedded on the upper end surfaces of the two side mounting plates 2 in this embodiment, and a plurality of second plug plates 41 are provided on both sides of the lower end surface of the top plate 4, and the plurality of second plug plates 41 on both sides respectively penetrate the side mounting plates 2 at the lower end; two second limit plates 42 are respectively provided on both sides of the lower end surface of the top plate 4, and the two second limit plates 42 on the same side correspond to the two first limit plates 12 at the lower end and are located on both sides of the sound-absorbing cotton 13, two L-shaped limit blocks 43 are respectively provided on both sides of the lower end surface of the top plate 4, and a mineral wool board 44 is commonly installed in the four L-shaped limit blocks 43, and two handles 45 are installed on both sides of the upper end surface of the top plate 4, and the two handles 45 are arranged in parallel.

[0027] In this embodiment, the mineral wool board 44 is set, which has a lower density and better sound absorption characteristics, and has good sound insulation performance. It can assist the setting of several sound-absorbing cottons 13 to make the noise reduction effect of the device better. The several second plug plates 41 set at the lower end of the top plate 4 are embedded in the two side mounting plates 2 at the lower end, which is convenient for installation and disassembly, and convenient for later maintenance and cleaning of the high-pressure fan 15 wrapped inside. The two handles 45 set on the upper end surface of the top plate 4 are convenient for carrying the equipment.

[0028] See also Figure 1-5 In order to make the noise reduction effect of the device better, two long bolts 22 are respectively penetrated on the two side mounting plates 2 in this embodiment, the two long bolts 22 at the upper end respectively penetrate the several second plug plates 41 located on both sides of the lower end surface of the top plate 4, and the two long bolts 22 at the lower end respectively penetrate the several first plug plates 11 located on both sides of the upper end surface of the bottom plate 1, and an anti-slip strip 141 is respectively installed on the two support plates 14.

[0029] In this embodiment, the long bolt 22 is provided, and by rotating the nut at one end of the long bolt 22, it is convenient to connect the plurality of second plug plates 41 and the plurality of first plug plates 11 that are interlocked with each other to the side mounting plate 2.

The vibration-damping feet 16 can reduce the noise and vibration caused by the vibration of the equipment during operation.

[0030] The working principle of the above embodiment is:

[0031] Before using the device, the user first connects the high-pressure fan 15 to an external power source, and then starts the high-pressure fan 15. The noise reduction effect of the device is better through the multiple sound-absorbing cottons 13 arranged between the two first limiting plates 12 on both sides of the upper end surface of the bottom plate 1 and the mineral wool boards 44 installed in the four L-shaped limiting blocks 43. The sound-absorbing cotton 13 has a streamlined arc shape, and the streamlined arc shape is used to change the propagation mode of sound waves on the surface of the object. Compared with a flat surface or a surface with many edges and corners, the streamlined arc surface can reduce the reflection and refraction of sound waves. It can flow more smoothly along the curved surface, so that the noise can be better absorbed or scattered, reducing the noise energy of propagation and reflection, and achieving the effect of reducing noise. At the same time, the mineral wool board 44 is a manufacturing material with good sound insulation performance. It has a low density and good sound absorption characteristics. When the high-pressure fan 15 is working, the four vibration-damping feet 16 arranged on the lower end surface of the base plate 1 are made of materials such as springs, rubber or air bags. The vibration-damping feet 16 can reduce the noise and vibration generated by the vibration during the operation of the equipment, and finally complete the noise reduction processing of the device.
