The rod structure is fixedly mounted on the main unit, and the airflow generated by the main unit flows in from the bottom end of the rod main unit 1. Since the air outlet is only the air outlet channel 7 around the rod main unit 1 and the top end is closed, the airflow generated by the main unit blows into the rod main unit 1 to form a pressure-equalizing cavity with a relatively high wind pressure, so as to ensure that the airflow is ejected from the air outlet channels 7 at the upper and lower ends of the rod main unit 1 at the same flow rate. After the airflow in the rod main unit 1 is heated, it is ejected from the air outlet channel 7 under the guidance of the air guide plate 9 on the air guide grille 2. Figure 6As shown, when the airflow ejected from the air outlet channel 7 reaches a certain wind speed, a negative pressure area will be formed at the section 4. Moreover, since the air guide grille 2 and the cover plate 3 are distributed in an annular shape, the extension direction of the air outlet channel 7 is arranged in a spiral radial shape as a whole. Therefore, the rod structure will form a negative pressure area that is distributed in an annular shape as a whole at the section 4 outside the cover plate 3. When using the curling device with the rod structure, it only needs to be close to the hair, and the hair will be wound to the outer surface of the cover plate 3 by the adsorption force generated by the negative pressure area.
