Zusammenfassung: | The air filter assembly comprises an air inlet pipeline, an air filter body and an air outlet pipeline which are sequentially connected, one section of the air inlet pipeline is an air inlet pipe noise reduction section, noise reduction materials are arranged in the air inlet pipe noise reduction section, one section of the air outlet pipeline is an air outlet pipe noise reduction section, noise reduction materials are arranged in the air outlet pipe noise reduction section, and noise reduction materials are arranged in the air outlet pipe noise reduction section. Compared with the prior art that a large-capacity resonant cavity does not need to be arranged in a compact cabin, so that the air inlet noise of the air filter cannot be effectively reduced, the large-capacity resonant cavity does not need to be arranged in the compact cabin, and the large-capacity resonant cavity does not need to be arranged in the large-capacity resonant cavity. The air inlet noise of the air filter can still be effectively reduc |
