In the above cleaning device, after the air extracting member 300 is started, the air enters the filtering mechanism 100 from the air inlet 101 of the filtering mechanism 100, the air is exhausted from the air outlet 102 of the filtering mechanism 100 after being filtered in the filtering mechanism 100, then enters the air extracting member 300 through the air extracting end of the air extracting member 300, enters the air exhausting channel 201 from the air exhausting end 310 of the air extracting member 300, and finally is exhausted to the outside from the air outlet 2121. In the above-mentioned cleaning device, the casing 210 has a portion opposite to the air exhaust end 310 of the air exhaust member 300, and the distance between the portion and the air exhaust end 310 of the air exhaust member 300 is smaller than the length of the air exhaust channel 201, so compared with the case that the air flow is exhausted to the outside through the casing 210 and the portion opposite to the air exhaust end 310 of the air exhaust member 300 after coming out from the air exhaust end 310 of the air exhaust member 300, the length of the air exhaust channel 201 is increased, and the noise generated by the cleaning device during operation can be effectively reduced.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
