[0024] refer to Figure 1-2 , a new type of muffler device, which is composed of two square mufflers with the same shape and size connected in parallel. A perforated plate 12 with micro holes is used inside the two mufflers to separate the muffler into a first chamber and a second chamber. The perforated plate 12 There is an asbestos layer on the surface, and through holes are evenly distributed on the perforated plate. and the noise reduction after the second chamber muffler, thereby increasing the noise reduction effect of the muffler. The sectional view of the muffler is composed of two square mufflers (such as figure 2 shown).
[0025] The inner cavity of the first chamber is provided with a mesh plate 11, and the first chamber is divided into the first upper chamber 3 and the first lower chamber 10 by the mesh plate 11, and the flange 1 is respectively connected to the first lower chamber 3 through the air inlet pipe 2. The first upper chamber 3 and the first lower ch...
