AI Technical Summary
Technical Problem
The existing fan muffler has a relatively simple silencing method and cannot further reduce noise.
Method used
The structural design includes an outer cylinder, a curved baffle, a conical shell, a cross silencer and sound insulation filling. The kinetic energy of noise is consumed by the rebound of the curved baffle and the conical shell, and the cross silencer and sound insulation layer are used to further reduce the noise.
Benefits of technology
The noise reduction effect of the fan inlet is enhanced, and the multi-layer structure design significantly reduces noise transmission and improves air flow characteristics.

Abstract
The utility model relates to the technical field of fan air inlet noise elimination, in particular to a fan air inlet noise elimination device which comprises an outer cylinder, a plurality of arc-shaped baffles are fixed to the position, close to one end, of the inner side of the outer cylinder, a conical shell is arranged beside the arc-shaped baffles, and a cross-shaped noise elimination plate is fixed to the position, located beside the arc-shaped baffles, of the inner side of the outer cylinder. The fan silencer solves the problems that an existing fan silencer is single in silencing mode, and noise cannot be further reduced.
