AI Technical Summary

Technical Problem

The existing fan silencer lacks filtering function, causing dust to enter the silencer, affecting the silence effect, and does not have the function of improving the sealing of the connection, resulting in wind noise leakage.

Method used

A silencer with filtering function is designed. By installing a filter assembly on the right side of the inner cavity of the silencer body, including a support rod, a filter mesh plate, a second spring, a telescopic rod, a third spring and a slap plate, combined with a sealing assembly such as a sealing ring, a circular cylinder, a first spring, a short rod and a connecting plate, the filtering and sealing effect is achieved.

Benefits of technology

Through the design of the filter component, dust is effectively filtered, the sound silence board is protected, and the sound silence effect is improved. Through the design of the sealing component, the connection sealing is enhanced, wind noise leakage is prevented, and the overall effect is improved.

Abstract

The utility model relates to the field of fan silencing, in particular to a silencer with a filtering function, which comprises a silencer body, a filtering component is mounted on the right side of an inner cavity of the silencer body, and sound-absorbing cotton is adhered to the inner cavity of the silencer body. Through cooperation of the supporting rod, the filter screen plate, the second spring, the telescopic rod, the third spring and the flapping plate, the silencer has the filtering advantage, when air enters the silencer body, the air is filtered through the filter screen plate, dust cannot be adsorbed to the silencing plate, when the air enters the silencer body, the filter screen plate can move on the supporting rod, and therefore the dust is prevented from being adsorbed to the silencer body. Meanwhile, a beating plate can beat a second silencing plate, a telescopic rod and a third spring are contracted, and therefore a filter screen plate moves left and right, and the filter screen plate is prevented from being blocked through vibration of the filter screen plate; and through cooperation of a sealing ring, a circular cylinder, a first spring, a short rod and a connecting plate, the connecting device has the advantage that the connecting sealing performance is improved.
