Optionally, the air inlet of the air supply barrel 30 is disposed at the first end portion 3081 and/or the second end portion 3082, the partition plate 307 includes a first connection section 3071 and a second connection section 3072, the first connection section 3071 extends along the length direction of the air supply barrel 30, one end of the first connection section 3071 is located in the air outlet duct 306, the first connection section 3071 is located at the outlet 303 side, and a gap is formed between the first connection section 3071 and the inner wall surface of the air supply barrel 30 opposite to the outlet 303, so as to facilitate the airflow to pass through; the second connecting section 3072 extends along the radial direction of the air supply barrel 30, one end of the second connecting section 3072 is connected with the other end of the first connecting section 3071, and the other end of the second connecting section 3072 is positioned at the outlet 303; the first connecting section 3071 and the second connecting section 3072 are sequentially arranged along the flowing direction of the air flow in the air outlet duct 306.

In this embodiment, the air inlet of the air supply barrel 30 is disposed at the first end portion 3081 and/or the second end portion 3082, the outlet 303 is disposed at the annular sidewall 308, and the air flow needs to flow along the length direction of the air supply barrel 30 first and then along the radial direction of the air supply barrel 30. The first connecting section 3071 is used for guiding the airflow at the air inlet of the blower barrel 30 to flow to the second connecting section 3072, and the second connecting section 3072 is used for guiding the airflow at the first connecting section 3071 to flow to the outlet 303.

The third connecting section 3073 is arc-shaped, so that the flowing resistance of the airflow is small, and the loss of the airflow flowing process is reduced.

Alternatively, the number of the partition plates 307 is plural, and the plural partition plates 307 are sequentially provided at intervals in the longitudinal direction of the air feed tube 30.

Meanwhile, the distance between the first connecting section 3071 close to the air inlet of the air supply barrel 30 and the air outlet duct 306 away from the outlet 303 is relatively large, so that more air flows into the sub air outlet duct 3061 far away from the air inlet of the air supply barrel 30.
