[0023] In order to make the purpose, technical scheme and effect of the utility model more clear and definite, the utility model is further explained in detail below with reference to the drawings and examples.It should be understood that the specific examples described here are only used to explain the utility model, and are not used to limit the utility model.

[0024] Please refer to Figures 1-7The utility model provides a kind of hair dryer, hair dryer includes hair dryer main body 1, and the inner ring air outlet 101 is equipped on hair dryer main body 1, and the inner ring air outlet 101 is separated by multiple first air deflector 111 Multiple first air duct 1011 with the axis of hair dryer main body 1 is inclined;Hair dryer main body 1 is also equipped with outer ring air outlet 102, and outer ring air outlet 102 is set around the inner ring air outlet 101, and outer ring air outlet 102 is separated by multiple straight second air deflector 112 Multiple second air duct 1021 with the axis of hair dryer main body 1 is parallel;The wind in hair dryer main body 1 is blown out by multiple first air duct 1011 Spiral wind, and the wind in hair dryer main body 1 is blown out by multiple second air duct 1021 Straight wind that surrounds spiral wind.

[0025] That is, because the hair dryer is now straight blowing type, and straight blowing type hair dryer is not only inconvenient for user to use but also low in blowing hair efficiency, and is easy to hurt hair, so the above structure forms straight wind as main airflow from the wind of fan main body through outer ring air outlet 102, and forms spiral wind as auxiliary rotating airflow from the wind of fan main body through inner ring air outlet 101, and outer ring main airflow can form airflow wall, so that inner ring auxiliary rotating airflow rotates inside outer ring airflow, so that spiral wind can fully contact with hair, further reduces the action of user to move hair with hand or comb while blowing hair, shortens drying time, and improves drying efficiency.

[0026] In the embodiment, first air duct 1011 has air inlet end 1012 and air outlet end 1013, and the wind in hair dryer main body 1 enters first air duct 1011 from air inlet end 1012, and the wind in first air duct 1011 exits to outside of hair dryer main body 1 from air outlet end 1013, and one end of first air deflector 111 close to air inlet end 1012 is vertically arranged with axis, as shown in the mark β, one end of first air deflector 111 close to air outlet end 1013 is arranged with axis at an angle α of 50°-70°, preferably, the angle α between one end of first air deflector 111 close to air outlet end 1013 and axis is set to 60°, and the axis is X axis as shown in the figure, and X axis is parallel to hair dryer main body. Figure 5 Figure 4 The angle setting makes the diameter of spiral wind larger and in the airflow wall formed by outer ring main airflow, and makes the length of spiral wind larger in the airflow wall formed by outer ring main airflow, so that a best blowing efficiency is achieved.

[0027] In the embodiment, the number of first air duct 1011 is 1-2 times the number of second air duct 1021, preferably, the number of first air duct 1011 is about 1.5 times the number of second air duct 1021, that is, the number of air ducts of inner ring is larger than the number of air ducts of outer ring, and such number cooperation is best for user to use to dry hair with the highest efficiency.​

[0028] In this embodiment, the number of first air outlets 1011 is 6-12, the number of second air outlets 1021 is 4-8, preferably the number of first air outlets 1011 is 10, and the number of second air outlets 1021 is 8, that is, the number of air outlets in the inner ring is greater than that in the outer ring. Such a number setting can make the air speed of the hair dryer and the number of rotations of the rotating air flow reach an optimum. If the number of first air outlets 1011 is only 1-5, the rotating speed of the rotating air flow is too slow, and the efficiency of blowing hair will be relatively low. If the number of second air outlets 1021 is only 1-4, the air flow wall is not strong enough. If the number of first air outlets 1011 is set to more than 12, the rotating speed of the rotating air flow is too fast, and the hair is easy to knot. If the number of second air outlets 1021 is more than 8, the air speed is too fast, and the pressure is large, so the user's scalp will feel uncomfortable under the wind pressure. Therefore, it is recommended that the number of first air outlets 1011 is 6-12, the number of second air outlets 1021 is 4-8, and the number of first air outlets 1011 is 10, and the number of second air outlets 1021 is 8. Such a number setting has a higher efficiency of blowing hair, and the user's scalp will not feel too strong pressure.

[0029] In this embodiment, the thickness of the second air guide plate 112 is in the range of 1-2.5 mm, and the thickness of the first air guide plate 111 is in the range of 1-2.5 mm, and preferably the thickness of the second air guide plate 112 is 1.2 mm, and the thickness of the first air guide plate 111 is 1.2 mm. The thickness range of the second air guide plate 112 and the first air guide plate 111 will affect the compactness of the air blown out of the hair dryer after passing through the first air duct and the second air duct. The thicker the thickness range of the second air guide plate 112 and the first air guide plate 111, the lower the compactness of the air blown out of the hair dryer after passing through the first air duct and the second air duct, and the air force is not enough. The thinner the thickness range of the second air guide plate 112 and the first air guide plate 111, the more the air force is gathered, and the use effect is better. In the case of ensuring the strength of the second air guide plate 112 and the first air guide plate 111 that can support the air force, it is as thin as possible.

Because spiral wind needs faster flow to reach the scalp at the same time as straight air, it gives the user a consistent sense of air speed. If the flow of spiral wind is equal to or lower than that of straight air, the user will feel the air speed in a regional way, which will bring the user an uncomfortable feeling, and also reduce the efficiency of blowing hair.

[0031] In this embodiment, the lowest wind speed of the air from the hair dryer body 1 through the second air outlet 1021 is 15 m / s, and the highest wind speed of the air from the hair dryer body 1 through the second air outlet 1021 is 10 m / s, so that the spiral wind and the straight wind reach the scalp at the same time, and the user has a consistent sense of wind speed.
