Due to the guiding function of the first guide wall 170 and the second guide wall 180, the airflow in the first air duct 110 can rapidly enter the second air duct 210 along the guide opening 160, thereby improving the drainage efficiency of the guide opening 160.
It should be noted that the flow guide opening 160 should be disposed close to the second air inlet 220, so that the air flow in the second air duct 210 is accelerated when entering the second air inlet 220, and the air flow in the second air duct 210 can be blown out from the second air outlet 230 quickly. In addition, the first flow guiding wall 170 and the second flow guiding wall 180 may be parallel to each other to ensure the flow guiding effect, and the first flow guiding wall 170 should extend toward the flow direction of the airflow to prevent the first flow guiding wall 170 from extending into the second air duct 210 too deeply to block the flow of the airflow in the second air duct 210; the first guide wall 170 and the second guide wall 180 do not overlap or have a gap in the radial direction of the first air duct 100, so that the resistance to the flow of the air in the first air duct 110 to the second air duct 210 is reduced while the air is guided.

It is conceivable that the end surfaces of the air outlet ends of the first air duct 100 and the second air duct 200 may be provided with a filter screen 700, the filter screen 700 covers the first air outlet 130 and the second air outlet 230, and the air is double-filtered at the air inlet and the air outlet, so that the filtering degree can be improved.
In addition, in an embodiment of the present invention, as shown in fig. 4, the hair dryer further includes an ion generator 800, the ion generator 800 is housed in the second air duct 210, the ion generator 800 is configured to release ions, the ions may be blown out from the second air outlet 230 along with the air flow in the second air duct 210, and the ions may be negative ions, oxygen ions, water ions, or the like, so as to optimize the hair drying effect of the hair dryer and avoid frizzy hair.
The ion generator 800 may be disposed at one end of the second air duct 210 close to the second air outlet 230, so as to reduce the loss of ions in the second air duct 210, as shown in fig. 4, taking negative ions as an example, the ion generator 800 is a negative ion releasing needle, the negative ion releasing needle is connected to the negative ion module 900 through a high-voltage wire, and when the hair dryer is powered on, the negative ion releasing needle may release negatively charged ion particles, so as to neutralize positive charges in hair, eliminate static electricity from hair, and make hair smoother after being blown.
It should be noted that, the heated ions have a failure risk, in the present invention, the ion generator 800 is disposed in the second air duct 210, the airflow in the second air duct 210 is formed by natural wind, and has no heating effect on the ions, and because the airflow blown out from the first air duct 110 and the second air duct 210 has an obvious regional boundary line, the influence of the hot wind in the first air duct 110 on the ions is small, and the failure probability of the ions can be reduced. In addition, because the first air duct 110 and the driving air duct, and the second air duct 210 is a driven air duct, the flow velocity of the air flow in the second air duct 210 is smaller than that of the air flow in the first air duct 110, after the air flows out of the air outlet, the air flow in the external air-out region 240 is driven by the air flow in the central air-out region 140, and within a certain distance (10cm-15cm), the external air-out region 240 and the central air-out region 140 continuously keep an obvious limit, so that the hair can be alternately acted by cold air and hot air while the ions can effectively act on the hair.
