There are many arrangements of the first air flow channel 13 and the second air flow channel 23, and there are two main ways:

first, as shown in fig. 5, the first air flow channel 13 communicates with the non-end portion of the second air flow channel 23, that is, the first air flow channel 13 may communicate with the middle portion of the second air flow channel 23 or communicate near the end portion of the second air flow channel 23. In one embodiment, the first air flow channel 13 communicates with the second air flow channel 23 adjacent the end. The airflow in the first airflow channel 13 is driven by the driving fan 18 to smoothly flow into the second airflow channel 23, and then is blown out from the airflow outlet 24 of the second airflow channel 23. A small portion of the airflow entering the second airflow path 23 is temporarily retained at the end of the second airflow path 23 remote from the airflow outlet 24, which does not substantially affect the smooth outflow of the airflow from the second airflow path 23.

As shown in fig. 6, in the second type, the first airflow channel 13 is communicated with the end of the second airflow channel 23, and the airflow in the first airflow channel 13 is driven by the driving fan 18 to smoothly flow into the second airflow channel 23 and then blown out from the airflow outlet 24 of the second airflow channel 23. Compared with the first embodiment, the air flow entering the second air flow channel 23 in the present embodiment does not stay at the end of the second air flow channel 23, but directly blows out all air from the second air flow channel 23, the air blowing out from the air flow outlet 24 is larger, and the hair can be dried more quickly.

There are various configurations of the transition flow path 41, and the transition flow path 41 may extend in a straight line or may extend in a curved line. As shown in connection with fig. 7, in one embodiment, the transition flow channel 41 extends in a straight line. The air flow of the first air flow path 13 can smoothly pass through the transition air flow path 41 and flow into the second air flow path 23.

In another embodiment, as shown in fig. 8, the transition airflow channel 41 is curved, and the curved transition airflow channel 41 can provide better guiding effect than the straight transition airflow channel 41, and the airflow can enter the second airflow channel 23 more smoothly, so that the wind blowing from the airflow outlet 24 can be larger, and the hair can be dried more quickly.

The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above examples only show some embodiments of the present invention, and the description thereof is more specific and detailed, but not to be construed as limiting the scope of the utility model. It should be noted that, for those skilled in the art, various changes, substitutions and alterations can be made without departing from the spirit and scope of the utility model. Therefore, the protection scope of the present invention should be subject to the claims.
