Therefore, the first sound absorbing layer 51 cooperates with the inner and outer casings 2, 4, and can also block the noise leakage of the motor fan. Through the above description, the advantages of the present invention can be summarized as follows: 1. The flow path of the air outlet passage 22 of the present invention is very long and spiral, so that the air outlet 22 can effectively absorb the flow velocity of the air. Reduce the noise generated by air disturbances. 1. The first sound absorbing layer 51 of the present invention is disposed in the mounting groove ι 2 and the extension space. The second sound absorbing layer 52 is laid on the bottom wall and located in the air outlet channel 22, and the third sound absorbing layer is disposed. 53 is disposed in the air outlet passage 22 and covers the air outlet holes 21, so that the first, second, and third sound-damping layers 51, 52'53 can make the air outlet passage 22 a large part: Smooth surface of the exhaust air, and greatly reduce the surface of the irregular structural surface: 'And, the first, second, and third muffling layers 51, 52, 53 can absorb the noise generated by the air disturbance, therefore, the present invention produces (4) sound. μ is effective to reduce the venting of the exhaust air, and the absorbing sound is 3-5, because the inner and outer peripherals 2〇, 40 are double-covered on the dust collecting bottom drum 110, therefore, the μ peripheral 20 40 can also further isolate the noise generated by air disturbances. In summary, the vacuum cleaner of the present invention can effectively reduce the discharge sound by slowing down the flow speed of the air, so that the purpose of the present invention can be achieved. Not only can it absorb the disturbance of the air, but the above is only the preferred embodiment of the present invention. When 9 M330821 can limit the scope of the new implementation, that is, the scope of the new patent application and the new description The simple equivalent changes and modifications made by the content are still within the scope of this new patent.
