Specifically, when the airflow enters from the air inlet end 111 and flows through the guide plate 300, the airflow is forced to change the original advancing direction under the action of the second plate 320, and is guided to the silencing cotton 200, and the noise in the airflow is absorbed by the silencing cotton 200, so that the noise is reduced.

It can be appreciated that the first plate 310 is connected to the second plate 320 by a circular arc angle, which facilitates the air flow into the silencing cotton 200. The first plate 310 may be a straight plate or a bent plate, and may be set according to actual conditions.

Referring to fig. 3 and 4, in some embodiments of the present invention, the plurality of flow guiding plates 300 are provided, and a gap 330 is formed between two adjacent first plates 310, so that the second plates 320 can guide the airflow to the gap 330 and enter the silencing cotton 200. Specifically, a part of the airflow passes through the first flow guide plate 300, is guided to the notch 330 by the second plate 320, and then enters the silencing cotton 200, a part of the airflow bypasses the second plate 320, enters the bent part of the flow guide plate 300, then flows through the second flow guide plate 300 along the first plate 310, and is guided into the silencing cotton 200 by the second plate 320 of the second flow guide plate 300, and a part of the airflow further flows through the third flow guide plate 300, which will not be described repeatedly later. By arranging the guide plates 300, most of the air flow can flow into the silencing cotton 200, and the noise reduction effect is further enhanced.

Referring to fig. 2 and 3, in some embodiments of the present invention, the sound reducing cotton 200 includes a first sound absorbing cotton 210 and a second sound absorbing cotton 220, the first sound absorbing cotton 210 and the second sound absorbing cotton 220 are respectively attached to the two sides of the width direction of the air outlet channel 110, i.e. the first sound absorbing cotton 210 and the second sound absorbing cotton 220 are respectively disposed on the left and right sides of the air guide plate 300, so that the air guide plate 300 guides the air flow to the sound reducing cotton 200, thereby increasing the noise reduction effect. Correspondingly, guide plate 300 is provided with two sets ofly, and one of them a set of guide plate 300 corresponds the cotton 210 setting of inhaling the sound, leads partial air current to the first cotton 210 that inhales the sound, and another group of guide plate 300 corresponds the second and inhales the cotton 220 setting of sound, leads partial air current to the second and inhales the cotton 220 of sound for more air currents are guided the cotton 200 of amortization, thereby the air-out noise that significantly reduces.

Referring to fig. 3, in some embodiments of the present invention, two sets of flow deflectors 300 are arranged along the length direction of the air outlet channel 110 in a staggered manner, so that the air flow can enter the first sound-absorbing cotton 210 and the second sound-absorbing cotton 220 respectively, thereby improving the absorption of the first sound-absorbing cotton 210 and the second sound-absorbing cotton 220 to the noise in the air flow, wherein the noise is absorbed by the sound-absorbing cotton 200. Meanwhile, the air flow can be decelerated.

It can be understood that the two groups of flow deflectors 300 may be arranged according to the shape of the air outlet channel 110, so as to facilitate the air flow to be discharged from the air outlet end 112, and prevent the air flow from accumulating in the air outlet channel 110.

Further, two second plates 320 of adjacent group overlap along the width direction of air-out channel 110 at least partially, can increase the air current of introducing amortization cotton 200, simultaneously, also can slow down the air current to the noise reduction. Specifically, most of the air flow is guided to the first sound-absorbing cotton 210 by the second plate 320, a small part of the air flow bypasses the second plate 320 and enters the other group of the guide plates 300, and the other group of the second plate 320 guides the air flow to the second sound-absorbing cotton 220, so that most of the air flow can be absorbed by the sound-absorbing cotton 200. And each time the air flow passes through the second plate 320, the air flow is forced to change the advancing direction, so that the speed of the air flow is slowed down, and the noise of the air duct is reduced.

Referring to fig. 3, in some embodiments of the present invention, the silencing cotton 200 further includes a third sound-absorbing cotton 230, the third sound-absorbing cotton 230 is disposed at the air inlet end 111, and the air flow entering the air outlet channel 110 is subjected to preliminary noise reduction, so as to improve the noise reduction effect.
