According to the technical scheme, the damping particles 30 are arranged between the cavity wall of the accommodating cavity 10a and the compressor assembly 20, when the compressor assembly 20 works, vibration generated by the compressor assembly 20 can be transmitted to the damping particles 30, and the damping particles 30 in the accommodating cavity 10a can collide and rub with each other, so that vibration kinetic energy of the compressor assembly 20 can be converted into friction heat energy and is discharged through the cavity wall of the accommodating cavity 10a, vibration of the compressor assembly 20 can be relieved, and working noise of the compressor assembly 20 is reduced. And because the damping particles 30 surround the vibration source, the sound waves of vibration noise are transmitted through the damping particles 30 and then transmitted to the external environment in the transmission process, and the damping particles 30 attenuate the sound waves, so that the energy of the sound waves is reduced, and the working noise of the compressor assembly 20 is further reduced.

When the diameters of the damping particles 30 are set between 0.01mm and 5mm (for example, 0.01mm, 0.05mm, 0.1mm, 1mm, 2.5mm and 5 mm), mutual friction among the damping particles 30 can be better realized, so that vibration kinetic energy of the compressor assembly 20 can be converted into friction heat energy and discharged through the cavity wall of the accommodating cavity 10a, vibration of the compressor assembly 20 can be reduced, and working noise of the compressor assembly 20 is reduced. And because a plurality of damping particles 30 surround the vibration source, the sound wave of vibration noise is transmitted through the damping particles 30 and then transmitted to the external environment in the transmission process, and the plurality of damping particles 30 can attenuate the sound wave better, thereby reducing the energy of the sound wave and further reducing the working noise of the compressor assembly 20.
