By setting up the silencing chamber 8, noise transmission can be blocked, achieving a silencing effect. The silencing component 6 and the airflow guiding component 7 change the exhaust path, effectively preventing noise from being transmitted along the exhaust path, further improving the silencing effect. The exhaust path is as follows: Figure 3 As shown; An aluminum honeycomb plate 14 is fixedly installed at one end of the flow guide cone 12. The side of the aluminum honeycomb plate 14 away from the flow guide cone 12 has an arc surface structure, which can effectively block the transmission of noise. The inner diameter of the end of the silencing shell 5 away from the boiler 2 is smaller than the inner diameter of the other end of the silencing shell 5, which can make the exhaust volume more balanced.
