Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, but the multitude of different ways that this utility model can be defined by the claims and cover is implemented.
nullBelow with reference to Fig. 1 to Fig. 3, the application is described further，A kind of deafener with air-flow buffer effect as shown in Figure 1，Including housing 1、It is fixed on the first air inlet pipe 2 in described housing 1、It is fixed on the second air inlet pipe 3 in described housing 1 and is fixed on the exhaustor 4 in described housing 1，Also include air-flow buffer device 5，Described air-flow buffer device 5 is fixed in described housing 1，And be connected with the inlet end of described exhaustor 4，As shown in Figure 2，Described air-flow buffer device 5 includes case 51 and spoiler 6，Described spoiler 6 is fixedly installed in described case 51，The inner chamber of described case 51 is divided into ante-chamber 52 and back cavity 55 by described spoiler 6，Described ante-chamber 52 is connected with the open front 53 of described case 51，Described back cavity 55 is connected with the after-opening 54 of described case 51，As shown in Figure 3，Described spoiler 6 includes passage 61，Described ante-chamber 52 is connected by described passage 61 with described back cavity 55.
As depicted in figs. 1 and 2, described after-opening 54 is connected with the inlet end of described exhaustor 4, and the inner chamber of described open front 53 and described housing 1 connects.
As shown in Figures 2 and 3, described spoiler 6 also includes branch chamber 65, and described passage 61 and described back cavity 55 are connected together by described branch chamber 65.
As it is shown on figure 3, described spoiler 6 also includes flange 63 and adjutage 64, described flange 63 extends in described passage 61, and described adjutage 64 extends in described branch chamber 65.
Described spoiler 6 also includes passway 62, and described passway 62 is positioned at the left end of described passage 61.
As it is shown in figure 1, described first air inlet pipe 2 includes the first expansion tube 21, described first expansion tube 21 has several the first through holes 22, and the inner chamber of described first through hole 22 and described housing 1 connects.
