[0023] In order to make the purpose, technical solution and effect of the present invention clearer and more specific, the present invention is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0024] See also Figure 1-7 The present invention provides a hair dryer, which includes a hair dryer body 1, an inner ring air outlet 101 is provided on the hair dryer body 1, and the inner ring air outlet 101 is separated into a plurality of first air outlet channels 1011 inclined to the axis of the hair dryer body 1 by a plurality of first air guide plates 111; an outer ring air outlet 102 is also provided on the hair dryer body 1, and the outer ring air outlet 102 is arranged to enclose the inner ring air outlet 101, and the outer ring air outlet 102 is separated into a plurality of second air outlet channels 1021 parallel to the axis of the hair dryer body 1 by a plurality of straight second air guide plates 112; the wind in the hair dryer body 1 is blown outwards as spiral wind through the plurality of first air outlet channels 1011, and the wind in the hair dryer body 1 is blown outwards as straight wind enclosing the spiral wind through the plurality of second air outlet channels 1021; the plurality of first air guide plates 111 are arranged in an arc shape, such as Figure 5 The shape setting of the longitudinal section of the first air guide plate shown.

[0025] That is to say, because the current hair dryers are of the straight-blowing type, which are not only inconvenient for users to use but also have low efficiency in blowing hair and are easy to damage hair, the above-mentioned structure allows the wind from the fan body to pass through the outer ring air outlet 102 to form straight wind as the main airflow, and the wind from the fan body passes through the inner ring air outlet 101 to form a spiral wind as an auxiliary rotating airflow. The outer ring main airflow can form an airflow wall to make the inner ring auxiliary rotating airflow rotate inside the outer ring airflow, so that the spiral wind can fully contact the hair, further reducing the action of users using their hands or combs to push their hair apart while blowing their hair, shortening the hair drying time and improving the hair drying efficiency. The arc-shaped setting of the first air guide plate can better form a tornado, and the setting is simple, the cost is low, and the presentation effect is also good.

[0026] In this embodiment, the first ventilation channel 1011 has an air inlet end 1012 and an air outlet end 1013. The wind in the hair dryer body 1 enters the first ventilation channel 1011 from the air inlet end 1012, and the wind in the first ventilation channel 1011 is discharged to the outside of the hair dryer body 1 from the air outlet end 1013. The end of the first air guide plate 111 close to the air inlet end 1012 is perpendicular to the axis. Figure 5 At the β mark shown, the end of the first air guide plate 111 close to the air outlet end 1013 forms an angle α of 50°-70° with the axis. Preferably, the angle α between the end of the first air guide plate 111 close to the air outlet end 1013 and the axis is set to 60°. Figure 4 The X-axis shown is parallel to the hair dryer body. The above angle setting makes the diameter of the spiral tuft larger and within the airflow wall formed by the outer circle main airflow, and the length of the spiral tuft is larger within the airflow wall formed by the outer circle main airflow, so as to achieve an optimal blowing efficiency.

[0027] In this embodiment, the number of first air outlet ducts 1011 is 1-2 times the number of second air outlet ducts 1021. Preferably, the number of first air outlet ducts 1011 is about 1.5 times the number of second air outlet ducts 1021, that is, the number of air ducts in the inner ring is greater than the number of air ducts in the outer ring. Such a combination of numbers provides the best user experience and the highest efficiency in drying the hair.

[0028] In this embodiment, the number of the first air outlet 1011 is 6-12, and the number of the second air outlet 1021 is 4-8. Preferably, the number of the first air outlet 1011 is 10, and the number of the second air outlet 1021 is 8, that is, the number of the air outlets in the inner ring is greater than the number of the air outlets in the outer ring. Such a ratio setting can make the wind speed of the hair dryer and the number of revolutions of the rotating airflow reach an optimum. If the number of the first air outlet 1011 is only 1-5, the rotation speed of the rotating airflow is too slow, and the efficiency of blowing hair will be relatively low. If the number of the second air outlet 1021 is only 1-4, the airflow wall It is not strong enough. If the number of the first air outlets 1011 is set to more than 12, the rotating airflow will rotate too fast and the speed will be strong, so the hair will easily get tangled. If the number of the second air outlets 1021 is more than 8, the wind speed will be too fast and the pressure will be high. The user's scalp will feel uncomfortable under the wind pressure. Therefore, it is recommended that the number of the first air outlets 1011 be 6-12 and the number of the second air outlets 1021 be 4-8. The optimal number of the first air outlets 1011 is 10 and the number of the second air outlets 1021 is 8. Such a number setting will make hair blowing more efficient and the user's scalp will not feel excessive pressure.

[0029] In this embodiment, the thickness range of the second air guide plate 112 is 1-2.5mm, and the thickness range of the first air guide plate 111 is 1-2.5mm. Preferably, the thickness range of the second air guide plate 112 is 1.2mm, and the thickness range of the first air guide plate 111 is 1.2mm. The setting of the thickness range values ​​of the second air guide plate 112 and the first air guide plate 111 will affect the compactness of the wind 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 wind blown out of the hair dryer after passing through the first air duct and the second air duct, and the wind force is insufficient. The thinner the thickness range of the second air guide plate 112 and the first air guide plate 111, the more concentrated the wind force is, and the better the use effect is. They should be as thin as possible while ensuring that the second air guide plate 112 and the first air guide plate 111 can support the wind force.

[0030] In the present embodiment, the wind speed of the wind from the hair dryer main body 1 passing through the multiple first air outlets 1011 is consistent, the wind speed of the wind from the hair dryer main body 1 passing through the multiple second air outlets 1021 is consistent, and the wind speed of the wind blown out from the hair dryer main body 1 through the second air outlets 1021 is lower than the wind speed of the wind blown out from the first air outlets 1011, that is, the wind speed of the straight wind is lower than the speed of the spiral wind, because the spiral wind requires a faster flow rate to reach the scalp at the same time as the straight wind, giving the user a sense of consistency in wind speed. If the flow rate of the spiral wind is equal to or lower than the flow rate of the straight wind, the wind speed felt by the user will be regional, which will cause discomfort to the user and will also reduce the efficiency of blowing the hair.

[0031] In this embodiment, the minimum wind speed of the wind from the hair dryer body 1 through the second air outlet 1021 is 15m / s, and the maximum wind speed of the wind from the hair dryer body 1 through the second air outlet 1021 is 10m / s.
