Abstract
The utility model discloses a generator muffler and a generator. The generator muffler comprises a first chamber and a second chamber. A buffer cabin and two air inlet cabins communicated with the buffer cabin are arranged inside the first chamber. Air inlet pipes are connected on the two air inlet cabins. An air outlet pipe is connected on the buffer cabin. A backflow cabin and two flow cabins communicated with the backflow cabin are arranged inside the second chamber. The two flow cabins are communicated with the two air inlet cabins in a one-to-one correspondence way. The backflow cabin is communicated with the buffer cabin. When the generator muffler functions, an air flow enters the air inlet cabins through the air inlet pipes. A part of the air flow enters the buffer cabin while the other part sequentially passes through the flow cabins and the backflow cabin and finally arrives at the buffer cabin and interacts with the air in the buffer cabin in a convectional and buffering way. The air flow is further discharged through the air outlet pipe. By means of the multi-cabin type design, the air flow is fully decelerated during a flowing process. After being buffered by the buffer cabin, the air flow has the flow speed and the impact force significantly lowered. Therefore, the discharged air flow has a low and soft sound. Relatively great muffling effects are achieved. The utility model further provides the generator.
