Problems solved by technology

[0002] The existing exhaust system mainly uses the exhaust fan to ventilate the room, but the exhaust fan will generate noise, so the muffler is generally used for noise reduction. If the muffler is always placed on the outside during use, it is easy to accumulate dust, and The muffler is generally long and difficult to clean. After a long time, it will affect the ventilation efficiency and noise reduction effect of the muffler. After that, the muffler cannot be cleaned during use, which will lead to more and more noise during use, and the ventilation efficiency will be lower. The lower the lower, the more dust will cause the muffler to run smoothly, and it will be used for the existence of dust when the wind passes through, resulting in uneven force on the muffler and shaking, and although the muffler itself has a noise reduction effect, it will Reduce the efficiency of ventilation while reducing noise, thus affecting the ventilation rate of exhaust air

Embodiment 2

[0046] When the muffler body 42 needs to be cleaned after the fan has been muffled for a long time:

[0047] The first guide rod 15 will drive the first sliding block 41 to move, so that the muffler shell 4 will move, and then the muffler shell 4 will move to the position of the second port 12, and then the cross beam 45 will hit the blocking position 49, and then the fifth connecting rod 47 will drive the first rack 441 to move, the first rack 441 will move towards the direction of the first support plate 1, the first rack 441 will drive the first gear 442 to rotate, and then The first gear 442 drives the second rotating shaft 443 to rotate, the second rotating shaft 443 drives the first rotating shaft 46 to rotate through the transmission belt 444, and then the first rotating shaft 46 rotates on the second support plate 43, and the first rotating shaft 46 drives the rotating plate 5 to rotate After rotating, the rotating plate 5 will close the opening of the muffler shell 4,...

Embodiment 3

[0049] After the muffler body 42 is cleaned, it can return to the third port 13 for use again. If it needs to be shut down, it will reach the first port 11, and then the inside of the muffler body 42 will be kept sealed by the second sealing member 23.

Embodiment 4

[0051] When the muffler body 42 returns to the third port 13 after cleaning, the first rack 441 will be reset under the action of the second telescopic rod 48 and the first spring 481, so that the entire rotating plate 5, the second Two pipe fittings 6, cleaning structures 7 and 8 are reset, so that the baffle plate 54 is opened again, and then it will cooperate with the first cleaning rod 97 to clean up, and then the dustproof plate 61 will blow out air from the inside The fan blade 52 is cleaned by blowing, and then the fan blade 52 rotates to make the second pipe 6=baffle plate 54 clean the dustproof plate 61 to avoid the dustproof plate 61 from being blocked.

Abstract

The invention discloses a silencing structure for improving ventilation efficiency and ventilation stability of a ventilation system. The silencing structure comprises a first supporting plate arranged in an indoor wall body, a first through opening, a second through opening, a third through opening, an air exhaust fan arranged in the third through opening, a sealing element arranged in the first through opening, a dust suction box arranged at the second through opening, a silencer shell, a silencer body, a driving assembly and a through hole formed in the middle of a rotating plate, a supporting frame fixedly arranged in the through hole, and fan blades are connected to the supporting frame, wherein the first through opening, the second through opening and the third through opening are formed in the first supporting plate; by arranging the rotating plate and a baffle, the exhaust efficiency can be improved, meanwhile, the silencer body can be cleaned, and the ventilation stability of the silencer body and the silencing effect of the silencer body are better guaranteed; and a second pipe fitting and a cleaning structure are arranged to clean the fan blades on the baffle, so that the fan blades can better assist the air exhaust fan to exhaust air, and the exhaust effect is better guaranteed.
