As shown in fig. 7, the air duct member 100 is structured such that a part of the air supplied from the downstream air duct cavity 112 flows forward to the first air outlet frame 2, another part flows upward to the second air outlet frame 3 (air duct flow path shown by a single arrow in fig. 7), and the whole air supplied from the second air supply duct 12 flows forward from the rear to the first air outlet frame 2 (air flow path shown by a double arrow in fig. 7). Therefore, the airflow in the first air supply duct 11 can flow from the upstream air duct cavity 111 to the downstream air duct cavity 112, one part of the airflow in the downstream air duct cavity 112 flows to the first air outlet frame 2, the other part of the airflow flows to the second air outlet frame 3, and the airflow in the second air supply duct 12 only flows to the first air outlet frame 2 and does not flow to the second air outlet frame 3.
Therefore, only the first air supply duct 11 provides air flow to the second air outlet frame 3, and the second air supply duct 12 does not supply air to the second air outlet frame 3, so that the problems that the second air supply duct 12 interferes with the air supply from the first air supply duct 11 to the second air outlet frame 3 and the first air supply duct 11 interferes with the air supply from the second air supply duct 12 to the first air outlet frame 2 due to different air supply directions of the first air supply duct 11 and the second air supply duct 12 can be avoided.

Meanwhile, the air guide ring 13 is arranged at the first air inlet 17, and airflow entering the second air supply duct 12 can be guided through the air guide ring 13, so that the airflow flows more orderly, the flowing smoothness of the airflow is improved, the air supply noise is favorably reduced, and the air output is favorably increased.
In some embodiments of the present invention, the flow area of the air guiding ring 13 gradually decreases in the flow direction of the air flow in the second air supply duct 12. For example, as shown in fig. 2, in the flow direction of the air flow in second air duct 12, air-guiding ring 13 extends toward the direction close to the central axis of air-guiding ring 13. It can be understood that, by gradually reducing the flow area of the air guiding ring 13 in the flow direction of the air flow in the second air supply duct 12, the impact of the air flow on the inner wall of the air guiding ring 13 can be reduced, which is beneficial to reducing the noise value.
Alternatively, the curved surface body surrounded by the inner wall surface of the air guiding ring 13 has a horn shape or a circular truncated cone shape. Simple structure and convenient processing.

Therefore, the air supply to the second air-out frame 3 by the downstream air duct cavity 112 can be simply and effectively realized without influencing the air outlet of the second air supply duct 12, and the interference of the second air supply duct 12 to the air supply of the downstream air duct cavity 112 to the second air-out frame 3 can be avoided.

That is, the first air supply duct 11 and the second air supply duct 12 may be formed between the first casing 1b and the second casing 1 a. Therefore, the structure and the assembly steps of the air duct shell assembly 1 can be simplified, and the production efficiency is improved.
Further, a second air inlet 18 communicating with the upstream air duct chamber 111 of the first air supply duct 11 is formed in the first casing 1 b. The first air-out frame 2 may be integrally formed on the second housing 1a and opened forward. As shown in fig. 1, the second air-out frame 3 may include a rear frame integrally formed on the first casing 1b and a front frame integrally formed on the second casing 1a, when the first casing 1b and the second casing 1a are spliced in place, the rear frame and the front frame are spliced in place to form the second air-out frame 3, and the second air-out frame 3 is opened upward.
