Technical Field

[0001] The utility model relates to the technical field of household electrical appliances, in particular to a hair curling accessory and a hair curling device. Background Art

[0002] As a kind of hair design, curly hair style is increasingly sought after and loved by everyone. When using traditional techniques to design curly hair, it is generally necessary to use a hair dryer in combination with a curling comb, or a manual clamp-type curling iron. These traditional techniques require users to manually wrap the hair around the curling iron, and then use the curling iron to heat the wrapped hair to achieve curling, which is time-consuming, and these techniques cannot be completed by non-professionals, and the curling effect cannot be guaranteed.

[0003] Therefore, there are devices capable of achieving automatic curling in the prior art, such as air curling devices, which output airflow by setting an air outlet on the curling rod, so that the airflow flows along the outer wall of the curling rod to drive the hair to wrap around and be adsorbed on the curling rod, and the hair is heated by the curling rod, which can achieve automatic curling to a certain extent. Most of the air curling devices in the prior art have a fixed air outlet direction and can only achieve one-way curling. Therefore, when the user actually uses it, according to different curling styles, the user needs to change the posture of holding the curling device to complete the change of the air outlet direction, which makes the user's actual use more inconvenient.

By arranging an annular mounting seat on the outside of the inner cylinder for fixing the first rotating shaft, the position of the air guide blade can change relative to the main housing when it rotates around the first rotating shaft, and the change in the connection relationship between the air guide blade and the limiting column is used to change the air outlet direction of the device, thereby achieving air outlet effects of two different rotation directions.

[0014] In one embodiment, the number of the air guide blades is multiple, and the multiple air guide blades are spaced apart along the circumference of the inner tube, and further comprises a rotating cover, the rotating cover is coaxially arranged on the side of the inner tube away from the air inlet, the rotating cover is movably connected to the air guide blades of the multiple air guide blades, and the rotating cover can rotate relative to the inner tube around the central axis of the inner tube to drive the multiple air guide blades to rotate synchronously around the corresponding first rotating shaft.

[0015] In one embodiment, a positioning plate is formed on one side of the air guide blade facing the inner cylinder, the positioning plate is provided with an axial hole communicating with the air passage cavity, and the first rotating shaft passes through the axial hole.
