Detailed ways

The present utility model will be further described in detail below in conjunction with the accompanying drawings.

As shown in Figures 1-2, a muffler device for ventilation and air conditioning that is easy to install includes a muffler pipe 1, one end of the muffler pipe 1 is connected with a number of fixing structures around it, and the inner wall of the muffler pipe 1 is on the inner wall. A sound insulation layer 2 and a sound absorbing cotton 1 3 are connected in sequence, the sound insulation layer 2 is provided with a vacuum plate 4, and both ends of the muffler pipe 1 are connected with a support structure, and the two sides of the support structure are symmetrically connected with each other. There is a sound-absorbing mesh panel 5, and a number of deceleration plates 6 are connected in the muffler pipe 1 between the two support structures. The deceleration plates 6 are arranged in a staggered manner, and the muffler pipe 1 is away from one end of the fixed structure. An air outlet pipe 7 is connected, and the other end of the air outlet pipe 7 is connected with a dust cover 8 .

The fixing structure includes a fixing plate 1 10 connected to the side wall of the muffler pipe 1, and a fixing plate 2 11 matching the fixing plate 10 is connected to the external air conditioner.
